WINDOW-CONTROLLING DEVICE.

Application filed June 18, 1920. Serial No. 390,056.

To all whomit may concern:

Be it known that I, STANLEY W. NICHOL- soN, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Window-Controlling Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

' The invention relates to devices for raising and lowering windows, and more particularly windows of automobiles or other vehicles.

Among the objects of the invention are; to provide a device of the aforesaid character which may be compactly mounted upon a vehicle door between the outer casing and inner trimming; to provide adjacent pivot points upon a single support for a counterbalanced spring lifter arm and a control arm for the lifter arm, angularly engaging the latter; to provide a connection between the control arm and lifter arm and adapted to either operate the latter from the former or automatically lock the device to maintain its position of adjustment: and to provide a location for the locking means remote from the actuating means. The device herein described is especially applicable for use in connection with,

a type of windows commonly used in closed automobiles, and adapted to be opened by a lowering movement.

Although the invention will'be fully described in the following specification, I do not wish to be limited to the preferred embodiment shown as in its broader aspects it is capable of embodiment in numerous forms.

In the drawings:

Figure 1 is an interior View of a door of a closed car to which the inventionis applied to control a window in the upper portion of said door, the upper limiting position of the device and the corresponding closed position of the window being shown.

Figure 2 is an enlarged top view of the lifter device in its mid-position of adjustment;

Figure 3 is a corresponding view in side elevation;

Figures 4 and 5 are detail views, showing the positions of the pivoted locking dog and indicating the travel thereof, upon upward and downward actuation respectively of the door having the window B and frame G and being of the usual hollow construction.

Within said door, is arranged a lifter device D, attached to the frame C preferably by a bracket E upon which the lifter arm F and control arm G are pivotally mounted at F and G respectively. The lifter arm F as shown is provided at its pivotal end with a slightly curved portion F and at its outer end with an enlargement or head F which formation of the ends is preferable for the installation of a counterbalance spring means comprising the springs H secured at their outer ends to the head F and at their inner ends to a wire anchorage member J, which in turn engages a fixed pin K upon the bracket 1].. Upon the head F is journaled a roller L, which transmits the weight of the window B to the lifter arm by engaging a metal channel L secured to the lower edge of said window and a rectangular dog M is also pivoted upon said head at M and engages in a slot N in the outer end portion of the control arm G, the upper and lower edges of said slot being formed with reversely arranged ratchet toothed racks N. Said dog is acted upon by spring M coiled upon the pin M and tending to shift the dog to the diagonal locking position shown in Figure 2.

In the construction thus far described, the weight of the window B, acting upon the lifter arm F through the roller L is counterbalanced by the pull of the springs H upon said arm, so that little effort is needed to shift the window either up or down. To apply this efifort and to also control the locking means, there is provided an operating lever O, secured to the control arm G by bolts 0, the trimming being cut away at the attachment point, to permit the lever to extend through and be operated at the inside of the door. The slot N in the con trol arm G is slightly wider than the dog M, engaging therein, so that said dog may slide along either rack N without engaging the other or may assume the locking position shown in Figure 2 wherein it is inclined to both racks.

Upon-rotation of the o erating lever O, the control arm G is similarly rotated and relative movement occurs between the connected ends of the control arm and lifter arm, since said arms have different ivot points. Thus, the dog M as the contro arm is swung upward, will bear against the lower rack N, as shown in Fi ure 1 and will slide outwardly in the slot .L while upon downward actuation of the control arm, said dog assumes the position shown in Figure 5 and slides inward in the slot N. Thus, it is seen that adjustability of the dog M in the slot N permits the necessary relative movement between the control arm and lifting arm when the former is actuated and that the teeth N do not interfere with this adjustability. The do M additionally functions to automaticali y lock the device, upon release of the lever which it does by assuming the position shown in Figure 3, to which osition it is shifted by the coiled spring The modification shown in Figure 6 provides smaller teeth in the racks forming the edges of the slot and thus secures a more silent operation, since, when sliding against either of said racks, the dog bears always upon several of the rack teeth and consequently cannot give rise 'to the slight clicking noise such as may occur as the dog in the first described form of the device drops from one tooth to another of said racks.

A desirable feature of the above described mechanism lies in the location of the locking means at a point remote from the actuating means, the stresses acting in the locked members being thus exerted longitudinally rather than transversely and a lesser strain being exerted upon the supporting bracket.

Also the device, when locked resists both upward and downward movement so that in case the counterbalancing spring exerts either a somewhat excessive force or an insufiicient force, the parts will, nevertheless, be maintained properly adjusted.

What I claim as myinvention is:

1. In a window liftin device, the combination with a pivotal li er arm, and a pivotal control arm for the lifter arm inclined thereto, of a dog pivoted upon one of said arms and engageable with the other forming a means for actuation of the lifter arm by the control arm and establishin a lock maintaining the lifter arm adjuste 2.
